38 Addisonia 



for the species along the coast north of Cape May which is as far 

 south as the writer has made field observations. In northern 

 stations of the range (Ohio, Presque Isle in Lake Erie, and along 

 the Seneca River near Weedsport and Savannah, N. Y.) this is the 

 only form represented. This type or race appears to be the one 

 most widely distributed at least in the area north of Cape May. 



The range of this species overlaps somewhat the ranges of several 

 species more exclusively southern and western in distribution. 

 Natural hybrids between these undoubtedly exist; certain of these 

 species have been hybridized in the production of races of horti- 

 cultural value.
